The onboarding trade-off
Sign-up is where you win customers. It's also where fraudsters get in.
Make checks too strict and genuine customers give up halfway. Make them too light and you're onboarding stolen and fake identities. You shouldn't have to choose.
Onboard more customers
Live guidance on the customer's phone catches blur, glare and bad framing before they submit, so genuine people pass first time instead of dropping off.
Stop identity fraud
Spots edited documents, printed photos, screen replays and fake cameras, and recognises a document or face that has already been used under another name.
Meet your KYC obligations
Every decision records what was checked, what was found and why, so you can show a regulator or auditor exactly how a customer was verified.
Review only what needs reviewing
Clear cases are approved or declined automatically. Only the genuinely uncertain ones reach your team, with everything they need on one screen.
What your customer does
No app to download. Just the phone in their pocket.
Designed to take less than three minutes, on any recent iPhone or Android.
